*HJDRIV -- PGPLOT Hewlett Packard [Desk/Laser] Jet driver
C+
SUBROUTINE HJDRIV (IFUNC, RBUF, NBUF, CHR, LCHR)
INTEGER IFUNC, NBUF, LCHR
REAL RBUF(*)
CHARACTER*(*) CHR
C
C PGPLOT driver for Hewlett Packard Desk/Laserjet device.
C
C Version 1.0 - 1989 Apr 09 - S. C. Allendorf
C Combined all drivers into one driver that
C uses a logical name to choose the format.
C Version 1.1 - 1989 Sept - B. H. Toby
C (1) adapt for PC version of PGPLOT
C (2) use alternate logical name definitions
C (3) support for DeskJet/ " Plus/ " 500
C (4) reduce page size to 10.25 to fix PGIDENT
C
C Version 1.2 - 1991 Aug - B. H. Toby
C Clean up and add code for GRIFB1 since the
C subroutine is not in GRPCKG as of PGPLOT V4.9d
C
C IBM PC / HP DeskJet printer usage
C Default file name is LPT1 (parallel port#1)
C Setup the port using MODE LPTn:,,P (parallel)
C or MODE COMn:96,N,8,1,P (serial)
C Use COMn/HJ or LPTn/HJ to send output directly to a device
C or FILE.EXT/HJ or d:\path\file.ext/HJ to send the output
C to a file
C Files can be written to disk and then copied to the printer.
C However, there is a problem in treating plot files, since they
C may contain ^Z (end-of-file) and other control characters. Use
C COPY file.ext /B LPT1:
C to print the file.
C Note that logical name PGPLOT_xx under VMS corresponds to MS-DOS
C environment variable PG_xxx
C Ported back to VAX/VMS, lines of code changed are indicated by a "C!" flag.
C=======================================================================
C
C Supported device: Hewlett Packard LaserJet, LaserJet+, or LaserJet II.
C DeskJet, DeskJet Plus, DeskJet 500
C
C Device type code: /HJ
C
C Default device name: PGPLOT.HJPLT.
C
C Default view surface dimensions: Depends on which driver settings are
C chosen, via logical names PGPLOT_HJ_MODE, PGPLOT_HJ_MAR, PGPLOT_HJ_SIZE
C and PGPLOT_HJ_PAGE.
C
C Resolution: Depends on which driver settings are chosen, via
C logical names PGPLOT_HJ_MODE or PGPLOT_HJ_RES.
C
C Color capability: Color indices 0 (erase, white) and 1 (black) are
C supported. It is not possible to change color representation.
C
C Input capability: None.
C
C File format: See the LaserJet & DeskJet Printer Technical Reference Manuals
C for details of the file format.
C
C Obtaining hardcopy: Use the command PRINT/PASSALL.
C
C Logical Name Usage:
C ------- ---- ------
C
C PGPLOT_HJ_MODE: use $ DEFINE PGPLOT_HJ_MODE HJnn
C
C where nn is a number 1 - NDEV inclusive. You may also use one of the
C equivalent names listed below.
C Thus $ DEFINE PGPLOT_HJ_MODE HJ01
C and $ DEFINE PGPLOT_HJ_MODE LHOR are equivalent (etc.)
C The equivalent names are an attempt to make the driver names make
C sense. They are decoded as follows:
C
C 1st character: P for protrait orientation or
C L for landscape orientation.
C 2nd character: H for high resolution (300 dpi) or
C M for medium resolution (150 dpi) or
C L for low resolution (100 dpi).
C 3rd character: B for a straight bitmap dump (subroutine GRHJ01) or
C O for an optimized bitmap dump (subroutine GRHJ02).
C 4th character: R for a rectangular view surface or
C S for a square view surface.
C
C A few notes are in order. First, not all of the possible combinations
C above are supported (currently). The driver that goes by the name of
C PHOT is a driver that puts out bitmaps suitable for inclusion in TeX
C output if you are using the Arbortext DVIHP program. The only drivers
C that will work with unexpanded LaserJet are HJ08 and HJ09. The other
C seven drivers require a LaserJet Plus or LaserJet II. Finally, do NOT
C attempt to send grayscale plots to the drivers that use the optimized
C bitmap dumps. Terrible things will happen.
C
C Driver Equiv Size (H x V) Resolution
C ------ ----- --------------------- ----------
C HJ01 LHOR 10.25 by 8.00 inches 300 DPI
C HJ02 PHOR 8.00 by 10.25 inches 300 DPI
C HJ03 PHOT 8.00 by 10.25 inches 300 DPI
C HJ04 LHBR 6.54 by 4.91 inches 300 DPI
C HJ05 PHBS 5.65 by 5.65 inches 300 DPI
C HJ06 LMBR 10.25 by 8.00 inches 150 DPI
C HJ07 PMBR 8.00 by 10.25 inches 150 DPI
C HJ08 PMBS 4.48 by 4.48 inches 150 DPI
C HJ09 PLBS 6.00 by 6.00 inches 100 DPI
C
C The following logical names will override the PGPLOT_HJ_MODE settings,
C if used.
C
C PGPLOT_HJ_RES: use $ DEFINE PGPLOT_HJ_RES x where x is H, M, L or V
C H or HIGH for 300 bpi
C M or MEDIUM for 150 bpi
C L or LOW for 100 bpi
C V or VERYLOW for 75 bpi
C
C PGPLOT_HJ_MAR: use $ DEFINE PGPLOT_HJ_MAR "xx.xx,yy.yy"
C where "xx.xx" and "yy.yy" are the vertical and horizontal
C margin dimensions in inches. The number of characters, including
C spaces preceeding and following the comma, should not exceed five.
C $ DEFINE PGPLOT_HJ_MAR "1.0,1.0" is valid
C $ DEFINE PGPLOT_HJ_MAR " 1.0 ,1.0" is valid
C but $ DEFINE PGPLOT_HJ_MAR " 1.00 ,1.0" is not valid
C
C PGPLOT_HJ_SIZE: use $ DEFINE PGPLOT_HJ_SIZE "xx.xx,yy.yy"
C where "xx.xx" and "yy.yy" are the vertical and horizontal
C plot dimensions in inches. The number of characters, including
C spaces preceeding and following the comma, should not exceed five.
C $ DEFINE PGPLOT_HJ_SIZE "10.,8." is valid
C $ DEFINE PGPLOT_HJ_SIZE "10.0 , 8.0 " is valid
C but $ DEFINE PGPLOT_HJ_SIZE " 10.0 ,8.0" is not valid
C
C PGPLOT_HJ_TEX: use $ DEFINE PGPLOT_HJ_TEX T
C if PGPLOT_HJ_TEX is defined with any value, TeX mode (see above)
C will be used.
C
C PGPLOT_HJ_NOFF: use $ DEFINE PGPLOT_HJ_NOFF T
C if PGPLOT_HJ_NOFF is defined with any value, the form feed
C needed to eject the final page will be omitted. This is useful
C for spooled printers -- it prevents wasted (blank) pages.
C
C PGPLOT_HJ_PAGE: use $ DEFINE PGPLOT_HJ_PAGE x where x is L or P
C Use L (or LANDSCAPE) for Landscape mode
C Use P (or PORTRAIT) for Portrait mode
C
C PGPLOT_HJ_OPT: use $ DEFINE PGPLOT_HJ_OPT x where x is O or C
C Use O (or OPTIMIZE) so that bitmap will be "optimized"
C Use C (or COMPRESS) so that bitmap will be "compressed"
C
C "Optimized" mode minimizes the memory usage for the LaserJet devices.
C This sometimes leads to a larger file than if optimization is not
C used. Optimized mode may not be used with the DeskJet devices.
C
C "Compressed" mode decreases the size of the bitmap file for later
C model HP devices, particularly the DeskJet devices.

REAL*4 RBUF(4)
C
C Draw a straight line segment from absolute pixel coordinates (RBUF(1),
C RBUF(2)) to (RBUF(3), RBUF(4)). The line either overwrites (sets to
C black) or erases (sets to white) the previous contents of the bitmap,
C depending on the current color index. Setting bits is accomplished
C with a VMS BISB2 instruction, expressed in Fortran as .OR.; clearing
C bits is accomplished with a VMS BICB2 instruction, expressed in
C Fortran as .AND. .NOT.. The line is generated with a Simple Digital
C Differential Analyser (ref: Newman & Sproull).

C Arguments:

C RBUF(3),RBUF(4) I R Ending point of line.
C ICOL I I =0 for erase, =1 for write.

INTEGER LUN, BX, BY
BYTE BITMAP(BX, BY)
C! INTEGER*1 BITMAP(BX, BY)
C
C Output raster for this page. This routine has been optimised to
C minimize the memory usage in the LaserJet. This sometimes leads to a
C larger file than if a straight bitmap approach had been used.
C
C NOTE: This subroutine is a kludge to make a 512K LaserJet produce
C full page plots at 300dpi. It will not always produce the plot
C on one page. If you overrun the memory restrictions, two pages
C will be printed, each containing parts of the plot. One must
C then resort to cut and paste techniques to restore the plot.
C Most simple line graphs do not come close to the memory limit,
C but sometimes a messy contour plot will. DON'T EVEN THINK
C ABOUT SENDING A GREYSCALE TO THIS SUBROUTINE!
